android - onFailure 方法中的 OkHttp 响应状态码

Question

当我以这样的异步方式使用 OkHttp 库时:

call.enqueue(new Callback() {
        @Override
        public void onFailure(Call call, IOException e) {
            e.printStackTrace();
        }

        @Override
        public void onResponse(Call call, Response response) throws IOException {

        }
    });

在onFailure方法中，如何获取响应状态码来区分不同的错误。例如，网络错误或服务器错误？

Answer 1

据我所知，onFailure 会在您没有响应时触发。因此，如果您收到错误，将调用 onResponse。您可以在 onResponse 中执行类似的操作:

@Override
public void onResponse(Call call, Response response) throws IOException {
    switch(response.code()){
    //your desired catched codes here.

   }
}

和official doc对于 onResponse 方法:

Note that transport-layer success (receiving a HTTP response code, headers and body) does not necessarily indicate application-layer success: response may still indicate an unhappy HTTP response code like 404 or 500.
